A lot of money for lights . . . and I hope they don't mess up the cruise control circuit.

You can buy a lot of replacement bulbs for what that cost.........its supposed to save you money in what way?

If they are made correctly, this might be pretty nifty (but see below). I made an LED replacement for my third brakelight on my 86 560. The flaw with just sticking an "LED bulb replacement" in is that the light is not even around the bulb, and you wind up with a bright red dot. This appears to be circuit boards and lots of big 10mm LED's, so it might wind up looking fairly even (I put 18 1.2 candela 10mm LED's in my brake light). My mod is completely reversible - I didn't destroy any of the original parts.

Another problem is current drain. My LED's draw about 250ma, and the original bulb was about 1.25 A. In order to fool the cruise and the "lights out" circuit, I had to put in a 15 ohm's worth of high-power "Sandbox" resistors, which get mighty warm.

Of course, mine (and probably this one) aren't DOT approved - this might matter in the investigation (and ultimate judgement) surrounding a major accident, God forbid. I'm just pointing this out.

If you calculate how much time the "instant on" nature of the LED's is worth vs the 0.5-0.75 seconds it takes a filament to attain full brightness, this amounts to a lot of feet at 70 MPH!

and to think I was in the process of building my own LED tails. Of course mine will include LED turn indicators as well.


EDIT: so whats this about disturbing the cruise control?

Curious if they are compatible with the "bulb out" indicator?

I like it. Very interesting. The bulb out indicator problem will be solved if they have included resistors in the housing circuitry.
$179 is not that bad considering some people are selling the tail light assembly for that price.

With that - I was playing with the LED's and turn signals. The current draw is so light it does not activate the flasher relay. What's the cure for that other than loading up resistance?

besides adding in a load resistor, replacing the standard blinker relay with an electronic one will do the trick.

The cruise control uses the brake lights filaments for a ground. When you step on the brakes, the 12 volts to light the lights makes the ground "go away" and the cruise control disengages. The LEDs may not show a ground to the CC the same way filament lamps do, unless that function is engineered into the new circuit.

Looks nifty, if you get them let me know how they workout! I have been looking for shop who can redo mines to retrofit customs LED's.

The LED bulbs are worthless, I purchased them in the past. Not even bright, you get that single "dot" of light. When you step on the break, it looks like the parking lamps. For the turn single it's more of a head ache, you need a conversion because the LED draws less power so the system thinks the bulb is blown so you get the fast blinker. For the side maker though, mines is okay so far.

For what it is worth, I was in Pepboys Auto Parts the other day and saw LED bulb replacements going for about $14. They look like they fit directly into the typical bulb sockets.

A lot cheaper. Whether they cause problems, I don't know.

they use very low quality LEDs and dont produce enough light. for example, actaul LED systems on the newer cars use like 30 or more superflux type LEDs and those "plug in types"...the ones that insert like normal bulbs have maybe 10-15 5mm LEDS. For those of you that may not know, standard 5mm LEDS are no where near as bright as Super Flux leds.
